In a successful example of extraordinary prediction (definition 2) [1]}, the top candidates from the considered ternary and quaternary inorganic solids (fig:tehrani2018-moduli) were selected for validation and confirmed to be ultraincompressible and to be superhard at low loads. [1]} also discuss nuances of measured performance such as whether hardness at low loads is a valid metric for superhardness considerations and to what extent the predicted compounds are viable for real-life applications.
